The Google Assistant is getting so "smart" that it's soon going to be able to place calls for you.

On Tuesday, at the Google I/O event, CEO Sundar Pichai demoed one experience where this sort of smart technology will be helpful. If you need to make an appointment for a haircut, for example, Google Assistant can call your barber and schedule a visit for you.

You don't need to talk on the phone at all.

In a pre-recorded demo on stage, the Google Assistant voice (which uses Google Duplex AI) sounded convincing enough -- not as robotic as it currently does -- that it successfully booked a hair appointment. In another demo, it was able to have a back-and-forth conversation with a restaurant in order to make a reservation.
